Viktor Kassai is a well-respected former football referee from Hungary. He was born on September 10, 1975, in Tatabánya, Hungary. Known for his calmness under pressure and efficient decision-making, Kassai officiated numerous high-stakes matches in both domestic and international football during his career.
Kassai began his refereeing career in the Hungarian League and was eventually promoted to the Nemzeti Bajnokság I, the top tier of Hungarian football, in 1999. His standout performances at the domestic level caught the attention of international football authorities, and he was added to the FIFA International Referees List in 2003, which allowed him to officiate international fixtures.
Kassai's international career is distinguished by his appointments to several major tournaments. He officiated matches in the UEFA European Championship in 2008 and 2012, as well as the FIFA World Cup in 2010. Notably, he was selected to referee the final of the 2011 UEFA Champions League between Barcelona and Manchester United, becoming the first Hungarian to referee a Champions League final since Sándor Puhl in 1997.
Throughout his career, Kassai was lauded for his command of the game, his understanding of football's laws, and his ability to communicate effectively with players. He was known for letting the game flow, preferring to use his cards sparingly.
In 2019, Kassai made the transition from field officiating to video assistant refereeing (VAR), becoming the head of the VAR project in the Hungarian football league. He officially retired from on-field refereeing in 2020 but has remained involved in football through his VAR work.
Kassai has also made contributions to the sport outside of officiating. He serves as the head of the Referee’s Technical Committee for the Hungarian Football Federation, where he's involved in the training and development of Hungarian referees.
